Subject [jira] [Commented] (MATH-1137) BOBYQA incorrect indexing
Date Wed, 16 Jul 2014 23:51:05 GMT

    [ https://issues.apache.org/jira/browse/MATH-1137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14064358#comment-14064358

Nigel Goodwin commented on MATH-1137:
-------------------------------------

My suspicion is being directed towards 

trustRegionCenterInterpolationPointIndex

In some cases this seems to be zero based, in others 1 based.

I was looking at the values of k in the loop and the values of the test at about line 790.
The skipped k values were not consistent between Fortran and Java, even when knew was set
the same at line 790....

Also KOPT v KNEW looks suspicious - the Fortran has a test against KOPT in ALTMOV, whereas
the java has a test against knew...

This is what I mean about the long hard slog comparing Java and Fortran. Unit tests are for
lazy people!
